New to modern pachinko, have a question

[Roddychop]

I've had a pachinko machine since I was a kid, it was given to me back in the 80's as a kid , but its never worked right. Recently I bought a newer machine off E bay.

Does anyone know what the machine is called ? Is there rules for play somewhere I can download ? There is a button that says " push " that makes a number of frogs jump up but can't figure out what this does ?

The thing will wake the dead so I ordered some L pad pots from the auction site.

I would like to learn all I can about the machine , so if you have any info I'd appreciate it.
